The invention provides a pair of invisible seamless tight pants capable of contracting
abdomen and slimming legs, which comprises a front piece (12), a rear piece (13) and side pieces (14), the front piece (12) and the rear piece (13) are bonded with the side pieces (14) through bonding strips, the front piece (12) and the rear piece (13) are bonded at side sewing lines through bonding strips, and the front piece (12) and the rear piece (13) are sewn at a lower
crotch line to form a pants body (1); the seamless tight pants are characterized in that eight sections A, B, C, D, E, F, G and H are formed on the lower limbs through different depths of needle pressing triangles by adopting a false rib fabric weave structure, and six pressure sections of first pressure, second pressure, third pressure, fourth pressure, fifth pressure and sixth pressure are respectively manufactured. Therefore, the pants fit the body, the close-fitting effect of shaping is realized. The invisible pressure tightening effect is achieved, the high elasticity of the fabric is improved, the use of chemical fibers is reduced, the environment-friendly and high-quality effects are achieved, the production efficiency can be improved, the quality can be improved, redundant abutted seams except inner side seams do not exist, and the pant are more fit and comfortable to wear.
